Anas bin Malik reported,

Anas reported that his grandmother Mulaykah invited the Messenger of Allah ﷺ to a meal she had prepared. He ate from it and then said, "Get up so I may lead you in prayer."I went to a mat of ours that had turned black from long use, and I sprinkled it with water. The Messenger of Allah ﷺ stood, with the orphan boy beside me and the elderly woman behind us, and he led us in two units of prayer.

أن جدته مليكة دعت رسول الله ﷺ لطعام صنعته فأكل منه فقال قوموا فلأصلي بكم فقمت إلى حصير لنا قد اسود من طول ما لبث فنضحته بماء فقام رسول الله ﷺ واليتيم معي والعجوز من ورائنا فصلى بنا ركعتين
